Geum plant named ‘Alabama Slammer’

ABSTRACT

A new, distinct  Geum  plant as shown and described, characterized by single to semi-double flowers of orange with red tips.

Latin name: Geum hybrid.

Cultivar name: ‘Alabama Slammer’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid of Geum plant named ‘Alabama Slammer’ characterized by single to semi-double flowers of orange and red. The new Geum was found as a naturally occurring, whole plant sport of ‘Tequila Sunrise’ U.S. Plant Pat. No. 21,514, patented, in Hebron, Ill. in 2006. The selection of the new plant was due to its' unique and multi colored single to semi-double flowers that have deeper orange petals edged in red compared to the parent plant with yellow petals edged in rose. The initial asexual propagation of the new plant was by division and took place at a nursery in Hebron, Ill. since 2007. Continued asexual propagation by division since that time has shown that the unique features of this new Geum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart (2001). The new Geum plant named ‘Alabama Slammer’ is characterized by single to semi double flowers of orange RHS 44A blending into red RHS N34.

The new Geum plant can be compared to the parent Geum ‘Tequila Sunrise’ (U.S. Plant Pat. No. 21,514). The new plant flower colors are orange RHS 44A blending into red RHS N34 while Geum ‘Tequila Sunrise’ has a bicolor flower of yellow RHS 9B blending into 46A.
